创业板上市公司内部控制鉴证有用吗?——基于信息披露与实施效果的检验

What Does Internal Control Attestation by GEM Companies Deliver Examination of Information Disclosure and Implementative Effects

深交所2009年发布规定,要求创业板上市公司至少每两年对内部控制实施一次鉴证。本文对创业板上市公司2009~2012年内部控制鉴证信息披露情况进行比较分析,并从会计差错更正、财务报表审计意见和操纵性应计利润三个方面检验内部控制鉴证的实施效果。研究结果发现,大多数公司的内部控制能够满足两年鉴证一次的要求,但是鉴证意愿并不强,鉴证报告规范性也有待提高;同时,虽然内部控制鉴证能够提高财务报告质量,但效果并不显著。因此,需要结合创业板的特性提高内部控制标准的可操作性,增强创业板公司内部控制鉴证意识,提高审计师对内部控制鉴证业务的正确理解和应用。

Along with the enforcement of internal control audit for Main Board, Shenzhen Stock Exchange has put forward specific requirements to internal control of SME Board and GEM Board. GEM companies should perform internal control attestation at least once two years. So, how internal control attestation of GEM is implemented？ What effect does internal control attestation have？ Taking GEM companies as an example, this paper compares and analyzes information disclosure of their internal control attestation between 2009 and 2012. Also, this paper tests the performance effect of internal control attestation from accounting error correction, financial statements audit opinion and discretionary accruals. We find that, most of GEM companies can meet the requirement of attestation once two years, but they have no strong willingness to attest. And the contents of internal control attestation reports need to be more normative. Meanwhile, although internal control attestation can enhance financial reporting quality, the effect is not significant. Therefore, this paper suggests enhancing GEM internal control standards＇ operability, strengthening GEM companies＇ consciousness, improving auditors＇ understanding and application of internal control attestation.
